Abstract: A mask and method of making a plurality of masks. The method includes forming a first sheet by joining a first material to a second material and forming a second sheet by joining a third material to a fourth material. The method further includes stacking the first sheet on top of the second sheet and connecting the first sheet and second sheet by joining the first material and the third material. Once the first sheet sand second sheet are joined, a mask or plurality of masks are cut from the stacked first sheet and second sheet, and the first material and the third material form the main body portion of the mask or plurality of masks, and the second material and fourth material form the fastening portion of the mask or plurality of masks.

Abstract: A surgical mask provides a wide range of wearers with a good fit and improved comfort, facilitates proper use of the mask, and reduces or eliminates fogging of eyewear, as compared with typical masks. The mask may include a pair of ties that are joined to the upper, central, and lower parts of either side of the body of the mask with the assistance of restraint members. The mask may also include a sealing member that reduces or eliminates gaps between the wearer's face and the upper part of the mask by forming a seal between the wearer's face and the mask in use. In addition, the mask may include a barrier panel that reduces or prevents the wearer's breath from escaping through the mask and rising to the wearer's eyewear.

Abstract: In one embodiment, a dynamically reconfigurable bandpass filter includes a resonator loop and a microfluidic channel proximate to the resonator loop, the channel containing a conductor, wherein the position of the conductor within the channel can be adjusted to change capacitive loading of the resonator loop and therefore change the frequencies that the filter passes. In another embodiment, a filter includes a second resonator loop having comprising switches located at discrete positions along a length of the second resonator loop, wherein opening and closing of the switches changes the effective length of the second resonator loop to change capacitive loading of the first resonator loop.

Abstract: An improved protective garment in accordance with the principles of the present invention provides an improved interface between a glove and sleeve of the protective garment. An improved protective garment in accordance with the principles of the present invention is easily incorporated with the protective garment and economically cost effective to implement and use. An improved protective garment in accordance with the principles of the present invention provides an impervious partial sleeve having a surface exhibiting non-adhesive friction when in contact with dry glove materials.

Abstract: A method of making a fluid impervious seam in a multilaminate fluid impervious medical fabric is disclosed. The multilaminate fluid impervious medical fabric includes at least two layers having different melting points, at least one of the layers is comprised of a fluid impervious material. The method includes overlapping two portions of the multilaminate fluid impervious medical fabric to form an overlapped region wherein the two layers having the innermost position in apposition to one another have a lower melting point relative to the melting point of the fluid impervious material layer. The two portions of multilaminate fluid impervious medical fabric are heat sealed together at the overlap at a temperature which is equal to or greater than the melting point of the innermost identical layers and which temperature is less than the melting point of the fluid impervious material layer.

Abstract: The present invention provides a gown 10 having a fastening structure which allows for easy securing of the gown 10 on a health care professional. The present invention provides a gown 10 having a front 14, two back side portions 16, 18, with two sleeves 20, 22 secured thereto. A tie 27 is provided that is attached to the gown 10. Secured to the front portion of the gown is an adhesive surface 25. The area of adhesion provided is preferably wider than the width of the tie 27 and of sufficient length to properly adhere the tie 27. To secure the gown 10 on the health care personnel, the tie 27 is extended around the back to the front area 14 and secured to the adhesive area 25.

Abstract: A microporous film can be made by adding a foaming agent to the components of a film material to create bubbles in the film. The microporous film can also be made by adding filaments to the components of the film material and dissolving the filaments to create the pores. In either process, the size of the pores can be controlled to be no greater than 0.027 .mu.m.

Abstract: Medical tubing carries on at least a portion of its length a water-activated lubricating coating of a hydrophilic thermoplastic resin which is adhesively compatible with the material of the medical tubing and polyvinyl pyrrolidone having a molecular weight of at least 200,000, in the form of a dispersed separate phase in the thermoplastic resin upon hydration. The polyvinyl pyrrolidone provides long-lasting lubrication when wet.
